In the 1960's the Swedish defense strategy was to fly as low as possible to avoid enemy radar and then fire anti-ship missiles on the invasion fleet. You are the pilot of a Viggen 37 attack aircraft on a training mission. The government has invested a lot of currency in you so you better not crash into trees, mountains, radio towers, lakes, buildings, or swedish steel birds that will destroy your aircraft. Remember there are no points for second place, but you will get points the lower to the ground you fly (below 30 m).
